ATTACHMENT F013. CIRCULAR COMES.

Application filed January 29, 1 917.

To all whom it may concern:

Be it known that I, SAMUEL HADFIELD, a citizen of the United States,residing at 518 Howard street, Lawrence, in the. county of Essex andState of Massachusetts, have in vented certain new and usefulImprovements in Attachments for Circular Combs, of which the followingis a specification.

My invention relates to circular wool combing machines in which thereare a large revolving comb circle and a small revolving comb circletangentially disposed inside thereof together with a dabbing brush ordabber and a brush plate proximate the tangential point between thelarge and small circles.

In such combs there are usually two or.

more small circles but I will describe my device as used in connectionwith one small circle and the large circle. Manifestly similar devicesmay be used in connection with more small circles if desired.

In such machines, both circles revolve in the same direction which Iwill assume to be from left to right, and I will call the side of bothcircles to the left of the tangential point the receiving side, and tothe right the delivery side.

In such combs there is a dabber or dabbing brush which reciprocatesvertically directly over the tangential point of the two circles. Thisdabber usually extends out toward the delivery side, while at the fiberreceiving side is a brush plate which slopes upward from at or near thetangential point. This plate is attached to a plate arm fixed to anypart of the machine and it, as well as the dabber, is adjustable.

Theoretically in a perfectly adjusted comb, the lower edge of the brushplate should adjoin the side of the dabber exactly at the tangentialpoint, but they are not usu-- ally so perfectly adjusted, and if theplate does not reach the tangential point, there is a very smallsubstantially V shaped space on the fiber receiving side between the twocircles into which noils, nips, specks, dirt, etc., drop or are forceddown by the dabber. Such material accumulates in the space until it ispicked up eventually by the fiber and the revolving circles and iscarried along to the injury of the work.

Moreover, the fiber which is forced down between the circles before itreaches the tangential point, does not get suificiently pulledSpecification of LettersPatent.

through the pins on the two circles, if at all, and the noils, dirt,etc, remain in the fiber after it is delivered by the circles. Thiscombing is therefore imperfect.

The fiber should not be forced in between the teeth of the two circlesbefore arriving at the tangential point to secure the most perfectcombing.

My invention is devised to fill up the substantially V shaped spacementioned and to prevent the wool, noils or dirt from getting downbetween the two circles before they reach the tangential point.

In the drawings Figure 1 is a plan view of part of a comb showing partof a. large and part of a small circle together with the brush plate anddabber. Fig; 2 is a side elevation, and Fig. 3 a plan view of my blade.Fig. 4b isa perspective showing the blade in position with the brushplate, dabber, and small circle removed.

A is the large circle and B is the small circle tangentially disposedinside thereof, the tangential point being represented by 10.

C is the dabber or dabbing brush which may be of any usual constructionof bristles or blades part being shown in full lines and the rest indotted lines.

D is the incline commonly used on such machines, F is the bracket, and Gis the incline bar allof which are old.

H is the brush plate supported on incline bar G in a well known manner.

My invention consists substantially of a curved tapering blade L whichis made of flat sheet metal with a shank 11 through which are slots 12,12 through which I pass set screws 18 into suitable threaded holes inbracket F to hold my blade in position and to permit its adjustmenthorizontally.

Preferably, my blade extends upward at 12 and again extends at 13 in adirection parallel with shank 11, the end 13 being curved to conformsubstantially with the curvature of the large circle and being taperedat the end to fill up the space between the teeth of the large and smallcircles on the fiber receiving side thereof.

I prefer to adjustably attach my blade to the bracket F but it may befixed to any other part of the frame of the machine in any mannerdesired.

I claim:

1. In a worsted comb having a large comb circle and a small comb circletangentially disposed inside thereof, a tapering blade fixed to theframe of the machine, the tapering end extending between the large andsmall comb circles.

2., In a circular combing machine having a large comb circle and a smallcomb circle tangentially disposed inside thereof, and a dabbing brushplate proximate the tangential point between the two circles on thefiber receiving side thereof, a curved tapering blade fixed to the frameof the machine and extending under the .dabbing brush Copies of thispatent may be obtained for plate into the space between the two circlesas described.

3. In a circular combing machine the combination with a large combcircle of a small comb circle tangentially disposed inside thereof, andmeans between said circles and under the dabbing brush plate forpreventing noils, nips and dirt from falling between the circles andthere accumulating to the injury of the work.

In testimony whereof I aflix my signature.

SAMUEL I-IADFIELD.
